% \def\JLaTeX{\leavevmode\lower.5ex\hbox{J}\kern-.15em\LaTeX}
% \pLaTeX\ is a Japanese \LaTeX\ format, which is adjusted/extended
% to be more suitable for writing Japanese documents.
% It requires \pTeX, a \TeX\ engine with extensions for
% Japanese typesetting, which is designed for high-quality
% Japanese book ``p''ublishing.\footnote{There is another
% old implementation of Japanese \LaTeX, called
% \JLaTeX\ (not available in \TeX\ Live).
% Also, MiK\TeX\ has another program \texttt{platex}, but
% it has nothing to do with our Japanese \pLaTeX!} The developent of
% both \pTeX\ and \pLaTeX\ was done by ASCII Corporation (and its
% successor ASCII Media Works\footnote{The \pTeX\ website:
% \texttt{http://ascii.asciimw.jp/pb/ptex/} (closed in 2016).}),
% so they are often refered to as ``ASCII \pTeX'' and ``ASCII \pLaTeX''
% respectively.
%
% In 2010, ASCII \pTeX\ was incorporated into the
% world-wide \TeX\ distribution, \TeX\ Live. Since then, \pTeX\ has
% been maintained/improved/changed along with \TeX\ Live sources.
% In recent versions of \TeX\ Live and W32\TeX\ (arround 2011),
% the default engine of \pLaTeX\ changed from original \pTeX\ to
% \epTeX\ (\pTeX\ with \eTeX\ extension).
% Also, the original \LaTeX\ itself is also frequently updated.
% On the other hand, \pLaTeX\ remained unchanged since 2006,
% which resulted in some incompatibility and limitations.
%
% To follow these upstream changes, we (Japanese \TeX\ Development
% Community\footnote{\texttt{https://texjp.org}}) decided to fork
% ASCII \pLaTeX\ and distribute the ``community edition.''
% The development version is available from
% GitHub repository\footnote{\texttt{https://github.com/texjporg/platex}}.
% The forked community edition is different from the original ASCII
% edition, so any bug reports and requests should be sent to
% Japanese \TeX\ Development Community, using GitHub Issue system.
%
% This document (platex-en.pdf) is a brief explanation of
% the \pLaTeXe\ community edition. It is somewhat of a historical
% document now, since \pLaTeXe\ came into existence in 1995
% (although the English translation has been done by
% Japanese \TeX\ Development Community since 2017).
% The detail of source codes are described separately in pldoc-en.pdf.

% \section{Compatibility with Other Formats and Older Versions}
% \label{platex:compatibility}
% Here we provide some information about the compatibility between
% current \pLaTeXe\ and older versions or original \LaTeXe.
%
% \subsection{Compatibility with \LaTeXe}
% \pLaTeXe\ is in most part upper compatible with \LaTeXe,
% but some parameters are adjusted to be suitable for Japanese.
% Therefore, you should not expect identical output, even though
% the same source can be processed on both \LaTeXe\ and \pLaTeXe.
%
% We hope that most classes and packages meant for \LaTeXe\ works
% also for \pLaTeXe\ without any modification. However for example,
% if a class or a package redefines a command which is already
% modified by \pLaTeXe, it might cause an error at the worst case.
% We cannot tell whether a class or a package works fine with
% \pLaTeXe\ beforehand; the easiest way is to try to use it.
% If it fails, please refer to the log file or a package manual.
%
% Some \LaTeX\ packages are known to be incompatible with \pLaTeX.
% For those packages, \pLaTeX-specific patches might be available.
% Please refer to the documentation of the \texttt{plautopatch}
% package (by Hironobu Yamashita).
